- All Implemented Interfaces:
- IChartDataPoint, java.lang.Cloneable
public class ChartDataPoint
- extends java.lang.Object
Allows to specify formatting of a single data point on the chart.
On a series, the ChartDataPoint object is a member of the ChartDataPointCollection.
The ChartDataPointCollection contains a ChartDataPoint object for each point.
Example:
Shows how to work with data points on a line chart.
@Test
public void chartDataPoint() throws Exception {
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
Shape shape = builder.insertChart(ChartType.LINE, 500.0, 350.0);
Chart chart = shape.getChart();
Assert.assertEquals(3, chart.getSeries().getCount());
Assert.assertEquals("Series 1", chart.getSeries().get(0).getName());
Assert.assertEquals("Series 2", chart.getSeries().get(1).getName());
Assert.assertEquals("Series 3", chart.getSeries().get(2).getName());
// Emphasize the chart's data points by making them appear as diamond shapes.
for (ChartSeries series : chart.getSeries())
applyDataPoints(series, 4, MarkerSymbol.DIAMOND, 15);
// Smooth out the line that represents the first data series.
chart.getSeries().get(0).setSmooth(true);
// Verify that data points for the first series will not invert their colors if the value is negative.
Iterator<ChartDataPoint> enumerator = chart.getSeries().get(0).getDataPoints().iterator();
while (enumerator.hasNext()) {
Assert.assertFalse(enumerator.next().getInvertIfNegative());
}
// For a cleaner looking graph, we can remove data points individually.
chart.getSeries().get(1).getDataPoints().removeAt(2);
// We can also strip an entire series of data points at once.
chart.getSeries().get(2).getDataPoints().clear();
doc.save(getArtifactsDir() + "Charts.ChartDataPoint.docx");
